Julian Capital is a deeptech seed fund investing across most deeptech sectors including chips, chemicals, energy, robotics, sensors, and medtech. Founded by Julian Shapiro (former VP of Marketing at Webflow), Julian Capital combines venture capital with the DeepChecks.vc platform, providing full-stack design execution and hands-on growth strategy support to portfolio companies.

Pre-seed deeptech co-investor that writes many fast $25K checks, partnering alongside top firms, offering speed, broad frontier-domain expertise (AI, robotics, space, biotech) and deeptech credibility.

1517 Fund is an "anti-establishment educational institution" that backs "dropouts, renegades, and sci-fi scientists" with a strong preference for founders without undergraduate degrees and deep-tech researchers working on ideas that would appear in science fiction. They operate as "the first believer" in companies at extreme inception, providing $50k-100k R&D checks before non-dilutive grants and running a pre-VC pipeline including micro-grants for weird projects, teen camps, and a 3,000+ hacker community they often know for years before writing checks.

Targets companies applying modern computation (AI, simulation) to agriculture, mining, manufacturing, health and defense, leveraging partners's hard-science and national-security expertise to navigate regulation and dual-use challenges.
